| Abstract | The dependence of the concentration of nonequilibrium defects arising while in service LEDs on the basis of AlGaN/ InGaN/GaN and AlInGaP heteresructures with quantum wells on the time of course of direct current and electrical modes has been established. Experimental results confirming the reliability of these dependences have been received. |
